Though I'm not an Aussie...I must say I feel sorry for you guys, as well as (gasp!, dare I say it?) TNT for having to deal with this sort of (in my opinion anyhow) blatant sensationalist garbage some folks are trying to pass off as "credible journalism".
It's as if they are painting over a picture. They take a picture of a quite innocent children's site and with choosing only a few select colors, make it into a raging casino.
If you are a parent (as I am) things in the world seem to take on a different appearance. I can understand that, it has happened to me too. But still, you can't shelter your kids from everything in the world. HOWEVER:
If your child becomes overweight, you shouldn't be blaming McDonalds.
If they start to smoke, the ads from Tobacco industries are not responsible.
If they get into a cult, Harry Potter isn't the man who did it.
If they get addicted to drugs, it's probably better not to sue the vitamin company for "introducing your child to drugs" by using colorful, candy flavored vitamins.
On the same token, If your child becomes a gambler, don't run and blame Neopets.
BLAME YOURSELF.
LACK OF DECENT parenting is what causes undesired behaviors and addictions. If you don't want to talk to your children about the dangers and problems of life, quit trying to find someone else to carry your burden when things go wrong. Sure, environment does indeed play a role, but c'mon...nitpicking everything to the smallest degree (as in the case in discussion at the moment) is a sure way to make something more desireable to a kid by making it an "evil taboo".
You are a parent, and you're not helpless. If you don't approve of what games your kids are playing online, GUESS WHAT? You have the right as a parent to monitor what they do. Not only is it your right, it's your DUTY. Don't like it? Forbid them to go to the site in question, but don't expect what YOU decide personally should be implicated on all the other children, that's a decision up to their parents to make....their view may differ from yours. You shouldn't be running to the newspapers saying "This site is bad for kids and needs to be stopped!". It isn't the media's job to decide what is and isn't appropriate for your children, IT'S YOUR JOB.
If you're just noticing TNT had these games and are feeling appalled by it, I'm more appalled that you allow your young children to surf the net without your supervision. I'm sure your kids seeing a game of Grarrl Keno is the LAST thing you should be worrying about if you allow them complete unsupervised internet access.
AND ON A FINAL NOTE TO TNT IF THEY HAPPEN TO BE READING:
You're under the microscope, guys. If I were you, I'd change these items into something else, quick...before these media dogs discover these to start freaking out over:
Red Wine
White Wine
Rose Wine
Grog Light
Walk The Plank
Man O War
Hogshead
...and so on.....
Okay, I'll get off now...hope I didn't step on too many toes.
